Audio Issue in nested timelines

Hello everyone,

I am encountering a strange and very frustrating bug in Davinci Resolve Studio 17.1.1 Build 9.

I am working on a documentary that is over 20 minutes long. In order to keep a clean main timeline, I am editing the different scenes inside their own separate timeline, which I then want to combine in the main timeline to make the final film. When I play back the timeline clips inside the main timeline, the audio skips, as if there were weird jump cuts, when of course there are none.

Now I thought this was merely a playback issue, but turns out these "audio jumps" are rendered out as well. And the audio even jumps from left to right at some places, it's an utter mess.

The audio is also delayed by a few frames. When I put a rendered version of my timeline audio under the audio of the nested timeline, the latter plays about half a second later even though the wave forms line up perfectly.

When I select all the clips inside the nested timeline, put them into a compound clip and use this one in the the main timeline instead of the nested timeline, it seems to work fine. However the problem is that Audio Track effects and volume are not copied into the compound clip, which eliminates my mix when working with compounds.

Has anyone else encountered this issue and is there any solution to it?

Thank you!

I've seen others report this, but I was never able to duplicate it.

All I can think to suggest is don't nest, Copy/Paste instead.

dealyed frame audio in nested timelines still exists in 18 beta

Hi, I am experiencing pretty much the same thing. I shot an interview and I prepared an intro on an different timeline, made a compound clip and copied into the final timeline where the interview was. Added some sfx and rendered. Audio is present in the intro and in the last part of the interview. The sync track is muted in the other part of the clip and only the music track and sfx are ok. Going back into the project I noticed that audio is missing sometimes at the beginning of the interview, sometimes at the end and sometimes you hear the sync track when the playhead hoovers above the intro...
Just upgraded to 18 and issue remains

I learnt about this issue the hard way possible. I was Exporting a TV series and the client asked to add music to the ST channel. Since I had the stems with the wanted music in the exact place I added it and nested both to create a new L and R. Inside Resolve it played fine and no issues were spotted. However, after exporting the episode we noticed that just in that part a Phasing issue was introduced. I could not believe Resolve couldn't do such a simple job.


Lesson learned here. Never again I will nest audio inside the software.

So the issue is the audio that shouldn't be inside any compound clip?
- I just tried to "decompose in place" the compound clip but it doesn't do any good.
-I also tried to export the timeline in a new project and nothing changed.
-Copying part of the timeline into another timeline (just the interview without compound clip) doesn't help also.
I guess I'll have to it all over again...

i thought it was fixed a while ago but now i'm seeing it again. I'm on 17.4, mac studio m1 ultra. This is why i went back to round-tripping

I'm experiencing exactly the same issue, running Davinci Resolve 18. I created a new timeline, then imported Timeline 1, and the sound crackles and stutters. I'm using a Macbook Pro running M1 and and using Davinci Resolve in native mode. I only have activated 4 plugin that are M1 compatible.
Guess for me currently the only way to get around this is to render each timeline before adding the render as a new clip.
Shame, since I got excited when I heard how Davinci Resolve lets you merge timelines into a new timeline.

I have a similar problem using latest Resolve Studio 18.1.4 B9 on Windows
I noticed that the "voice iso" effect applied to a track in Fairlight was dissapearing when the timeline was nested in another timeline.
That makes the nesting concept unreliable...

I hope this gets fixed.

18.1.4

Issue is only happening in one of my nested clips

Workaround:

Export audio from original timeline and underlay under the final timeline with all the nested clips.

The best workaround I've seen for nested timeline audio issues is to bounce mix to track in the nested timeline and then setup the bounce as the only output from that timeline. This will get picked up in the master timeline and can be processed further without worrying about nested audio processing (which doesn't appear to work very well in Resolve).
